well i finally found my boost leak today but it took some work, had to take off my bumper and the lower shield under the car so i could get to the vac hose that comes off the bottom of the turbo and goes to the intake manifold. it had a rip in it , so i replaced that and also got new plugs (denso iridum). after driving it i realize that my car has never run better since ive owned it
im sure a stock bumper would be alot tougher to get off and on, my rs4 front is held on with 6 screws
with out a chip im now hitting 10 pounds of boost
